ILO meaning in Regional ?

Ilocano (also Ilokano; ; Ilocano: Pagsasao nga Ilokano) is an Austronesian language spoken in the Philippines, primarily by Ilocano people. It is the third most-spoken native language in the country.

As an Austronesian language, it is related to Malay (Indonesian and Malaysian), Tetum, Chamorro, Fijian, Māori, Hawaiian, Samoan, Tahitian, Paiwan, and Malagasy. It is closely related to some of the other Austronesian languages of Northern Luzon, and has slight mutual intelligibility with the Balangao language and the eastern dialects of the Bontoc language.

The Ilokano people had their own distinct indigenous writing system and script known as kur-itan. There have been proposals to revive the kur-itan script by teaching it in Ilokano-majority public and private schools in Ilocos Norte and Ilocos Sur.
